Figs. 22 and 23 are diagrams showing in side elevations and in different positions the device for carrying the main wire toward the spool in such amanner that while it is fedcontinuously to the spooling mechanism, yet it is allowed before reaching this point to remain still at intervals of sufficient length to have the barbs applied. Fig. 24 is an enlarged perspective view ofthe barb-former, showing the finger in its outer position. Fig. 25 is a similar view, showing the finger in its inner position. Fig. 26 is a perspective view ot' a piece ofthe barbed. wire.

Our invention relates to a machine for putting barbs on wire for fencing' purposes.

Our invention 'consists in certain novel features hereinafter fully described and claimed.

Referring to the drawings, A represents the table of the machine, and A' the supportinglegs.

B represents the main shaft ofthe machine, journaled in boxes B', secured to the table. 0n one end of this shaft is a driving pulley, B2, and a cog-wheel, B3, thelatter of which en gages with a similar wheel, C', on the shaft of the spooling apparatus C,in which nothingnew is claimed. 0n the other end ot' the shaftB is a cog-wheel, D, which engages with a pinion, D', on the hollow shaft D2 of the barb-former, which isjonrnaled in Suitable boxes, D3,secured to the frame A, the tops of the boxes being removed in Fig. 3 and the barb-former shown in horizontal section.

The main wire E, from a suitable reel, E', passes through the hollow shaft, and the shaft is of different diameters, it being considerably thelargestat itsinnerend, whereitischanneled to receive the forming-fingerF, which basa pin, F', on its outer end. After insertingthe finger, the channel is closed above itby a dovetailed piece, F2, which holds the linger in place. This end of the shaft is also bored out to receive a bushing, G, which has aconical outer end, (see Figs. 24 and 25,) for the purpose hereinafter eX- plained, and it has a central opening, through As the finger tinishes the formation of the barb it has an endwise motion imparted to it, which causesit to recede into the hollow shaft, out ofcontact with IOO the wire, while the shaft continues to revolve, and immediately after it recedes it is thrust again to its outer positioinreadytoform another barb, the main wire in the meantime having been moved along the desired distance, as hereinafter described. This reciprocating niotion is given to the finger by the following means:

H is a collar fitting loosely over the reduced or smaller portion of the shaft, and is connected with the finger by meansofa set-screw, H', (see Figs. 3 and 6,) or by other suitable means. The collar is grooved to receive an annular ring or band, H2, to which the arms J of one end of a lever, J, are secured. The lever is fulcrumed to a post, J2, secured to the frame A, and its other end works in a groove, 1,ofa collar, I, secured to the end ofthe shaft B. The outer wall of the groove l is provided with a projection, 12, and the inner wall with a corresponding notch, 12, (see Figs. 3 and 4,) which, coming in contact with the end of the lever, moves the collar H outward, as shown in Fig. 4, causing the projecting part of the finger to recede into the shaft, as stated, and then as the projection l2 leaves the end of the lever it (the lever) is moved to its other position, as it fits the groove snugly, throwing the finger to its working position. 1t will thus be seen that the finger has a continual revolving and an intermittent reciprocating motion iinparted to it.

'We will now describe the device for interniittently feeding the wire from which the barbs are cut.

K is a block supported by and working in a suitable groove in the table A. The groove admits of an end-play of the block, and is lettered K.

K2 K2 are jaws pivoted to the top of the block, as shown, and having their rear ends so formed tliata V-shaped opening isleft betweenthem, and their faces are notched or serrated. L represents a wedge, which rests and has v a limited end movement on the block K, its

inner end fitting between the rear ends ot' the jaws. The top of the block is formed with a flange around the outside, forming a cup, in which thejaws and wedge fit.

M is a lever, pivoted at M to the top of the table, and connected at one end by means of an arn'i or link, M2, to the wedge L. The other end ot' this lever is connected by means ot' a link, M3, to one end of another lever, N, which is pivoted at N to the table, and which has on its other end a friction-roller, N2, which bears against an eccentric, N2,on the shaft B. With this connection between the sliding block K and the shaft B, it will be seen that the former will be moved inward each time the salient part ofthe eccentric N3 bears against the friction-roller N2, the wedge L first being moved inward, as it connects with the arm M, as described, pressing the notched ends of thejaws against the wire, which passes between them, as shown in Fig. 3, and shown plainly in Figs. 20 and 21, and thus the wire is moved toward the main wire with the block the necessary distance to give wire enough for one barb. Thewire passes through the tlanges of the ends of the block and through the wedge, as shown in Figs. 20, 21. )Vixen the block has thus been moved inward the salient part of the eccentric N3 is of sufficient length to hold it there until the finger has given theharb wire, witnwhich it then comes in contact, one bend around the main wire, and then the eccentric suddenly leaves the arm N, and a suitable spring, 0, beaiing against the leverM, (seeFigs. 3 and 4,) forces the wedge L back against the rear flange of the block, which loosens the grip of the clamps upon the wire, and then, as the wedge cannot move back farther, the block is carried outward, the wire slipping through it, for, as before stated, it has been made fast tothe main WlIe.

fe prefer placing springs PP between the side anges of the block and the rear ends of the jaws, (see Figs. 20 and 21,) which take the bearing of the notched ends of the jaws from the wire as soon as the wedge has been forced back; but these springs are not absolutely necessary,as thejawswonhl slip over the wire without them,though they would bcarslightly against it.

The ends of the levers M and N are adjustably connected together, preferably by means of bolts M4 and N4 passing through slots M5 and N5. (See Figs. 3 and 4.) This adjustable connection gives nieans for changiiigtlie |no"enient of `the block, and consequently the amount of wire fed at each operation. The barb-wire passes beneath the main wire, and the fingeigrcoining against its free end from beneath, beiidsit around the main wire twice, as shown in Fig. 11, and then retreatsinto the hollow shaft, as before described. Ininiediately after the block K has made its return movement, which takes place when the finger has bent the barb-wire around the inain wire once, and while the finger is completing its work, the barb is cut from the main body of the wire by knives constructed as follows:

Q is an inclined lever, pivoted to a post, Q', by means ot' a bolt, Q2, passing through a hole, Q2, of the lever. 'lhc post is secured to the top of the table. To the lower end of the Iever (see Figs. 1S and 19) are secured a knife, Q4, and a guideblock, Q5. The barb-wire passes through this guide block, and also through the lower end ot' the knife, as shown by dotted lines, and the knife has a beveled edge, which works against the beveled end of a stationary' knife, R, secured. to the table A by means of a plate, R', or by other suitable means. The hole through which the wire passes is so' located that the wire will come out through the bevel-edge of the knife Q4. This knife has an intermittent circular motion imparted to it by means of the upper end of the pivoted lever, extending over the shaft B and being struck by an eccentric cam, S, (see Fig. 15,) on the shaft B. As the cam strikes IOC IlO

IIS

the lever it lowers the end to which the knife is secured, imparting the said circular motion to the knife, which carries the wire down upon the stationary knife, whose sharp edge cuts it, giving to the barb the desired sharp point. The knife Q1 works in the space Q6 (see Figs. 3, 10, and 1l) between the end of the hollow shat't D2 and the stationary knife R. To force the wireover the stationary knife, (see Fig. 11,) the conical end of the bushing'G, before mentioned, is employed. As the finger wraps the barb-wire around the main wire twice, and as there is only room enough for one bend of the wire between it, when in its normal position, and the end of the bushing, it will he seen that the second bend will move the first bend forward by wedging between it the inclined face ot' the bushing, forcing the wire over the stationary knife before the knife Q4 descends. Not only does the bushing force the wire over the knife lt, but `by this lateral movement binds it in the opening of the knit'e Q4, thereby enabling the knife to cut it more easily. As soon as the cam S `operates the lever it leaves it, and the upper end of the lever is thrown down, thereby raising the knife Q4 by means of its own weight, assisted by a spring, Q7, secured to the upper end of the post Q', and bearing against a projection, Q8, on the upper end of the lever. In order that the lever will not bear or be pressed upon the shaft by the spring Q7, we secure an arm, Q9, to the end of the lever, or to the block or projection Q3, which, when the lever is not raised by the cam S, rests upon the table, as shown in Fig. 5, holding the lever up out of contact with the shaft B. As soon as the linger has completed the barb and the knives cut it oft' the main wire is carried forward the proper distance by mechanism which we will now describe.

The wire from the barbing device passes over a wheel or drum, T, between it and a wheel or drum, "l", and then beneath the wheel or drum T', from whence it passes to the spooling apparatus over the common vibrating wheel, U, which feeds it uniformly to the spool. The top of the wheel T works through a slot, T2, of the table, so that its periphery is on a line or nearly on aline with the barbing device. The wheels are preferably formed with circumferential grooves T3 T4, and their peripheries provided' with teeth or notches, which engage the barbs on the wirewhich tsin the grooves, thus giving to the wirea positive forward motion. If these wheels T T' -were both stationary, the main wire, power being applied to the wheels, would be moved continuously forward before reaching the wheels as well as after it leaves them; and to 'so arrange these wheels or their equivalents that the Wire will be fed to the spool continuously and at a uniform speed, while in' advance-ot' the wheels it is allowed to stand still atintervals of sufficient length to have the barbs applied, is one of the principal objects of our present invention. The means we have shownof accomplishing this end is: The wheel T' is rigidly secured to a shaft, V, which is journaled in suitable boxes, V', suspended by hangers V2, secured to the bottom of the table A. Power is applied to this shaft, preferably, by means of a cog-wheel, V3, thereon engaging with a worm, V, on a shaft, V5, journaled in boxes V6, suspended from the bottom of the table b v means of hangers V7. On one end of the shaft V5 is a pinion, V8, engaged by a cog-wheel, V9, on one end ot' a shaft, V10, journaled in boxes V, suspended from beneath the table by means of hangers V12. this shaft Vl0 is a cog-wheel, V13, similar to that V9, which engages with the wheel D on the shaft B. Thus the wheel T', which carries the main wire forward, is driven from the main shaft of the machine. The wheel T is journaled on a short axle, W, on the upper end of an arm, W',supported' by the shaft V. (See Figs. 22 and 23.) The arm Wl is connected by a suitable link, W2, to the lower portion of a lever, W3, which passes up through and is pivoted to the table A at W4, and whose upper end' has a lateral projecting pin, W5, which works in a groove, W6, of a collar, W", secured to the shaft B. The groove passes spirally around the collar until it has aboutsurrounded it, and then with a sharp change passes in the other direction, as shown in Fig. 3. As the pin worksin this groove,it will bc seen that the lower end of the lever Ws will be gradually moved toward the front end of the machine, carryingthe wheel T with it, and then, when the pin comes to the change in the direction of the groove, the lower end of the level' and wheel will be forced with a quick movement inthe other directionthat is, away from the frontend of the machine. The machine has its different parts so arranged that this quick forward movement of the wheel T 0ccurs just after each barb has been completed, and it carries enough of the main wire'forward to bringthe next barb in the proper place. Then, as the wheel T moves slowly backward, the spool takes up the slack beneath.

We prefer to assist the quick forward movement of the wheel T by a spring, X, connecting the upper end of the arm W' with the bottom of the table, back of the wheel. The arm V' and the lower end of the lever W3 are adjustably connected by the bolts securing the link W2 thereto, passing through slots W8 W9, as shown in Figs. 5, 22, and 23.

If it is desired to make twisted wire on the machine, as would generally be the case, the plain wire is taken from a spool, Y, secured to the front legs A' of the machine, (see Fig. 1,) and joins the main wire at the wheel T, from where they go on together, and are twisted by the spooling apparatus, as usual.

If desired, the barb-wire need not pass through the knife Q4, but the knife be placed high enough for the wire to pass beneath its lower end.
